I want to make interactive graph like this using Qt and C++ : http://jsxgraph.uni-bayreuth.de/wiki/index.php/Cubic_spline_interpolation
Any leads on how to do that ?
EDIT :
Okay, I’ve already tried my hands on the QGraphicsView class and qwt library. However, I find no easy way to introduce interactive-ness. Is there an easy way to do that ?
Start with the QGraphicsview framework and the diagram example
